Abstract

1420991 Exhaust gas purification catalysts DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 23 March 1973 [25 March 1972] 14156/73 Heading B1E [Also in Division Cl] An arrangement consists of catalysts elements having at least one bore extending through them, forming continuous flow paths which elements a shaped, hard-sintered mixture of #- and #-alumina and more than 50 wt% of oxides and/or oxidic compounds of at least two metals, one being chromium and the other(s) being vanadium, manganese, iron, chromium, nickel and/or copper. The elements may be extruded honeycombs and may be impregnated a platinum group metal and/or a barium compound. Reference has been directed by the comptroller to Specification 1138444.
